Oysters Can Hear And The Noise Is Stressing Them Out!

Have you ever been stressed living in a loud apartment or dorm? Well, you have something in common with oysters, only their dwelling is the ocean.PLoS One revealed new research this past week stating that the shelled creature is becoming increasingly stressed due to ocean noise pollution.

According to the New York Times, when an oyster hears a loud sound, they close their shells. Think of their exteriors like a door! They are able to prevent the harsh frequencies from irritating their existence. Previous to this study, scientists thought the bivalve mollusks would only close their shells if they were “feeling stressed or threatened.”

The author of the study, Jean-Charles Massbuau noted they “must be able to hear breaking waves and water currents.” These two items are highly important to the creature’s overall biological rhythm. Hearing the sound of the ocean is sort of like us listening for an alarm clock in the morning. It helps us out with our daily routine!

Since there has been an increase of various human activity, the ocean has been a noisy home. Oysters become stressed due to the increased sound and shut their shells. Why is this so important? Well, Jean-Charles said, “To hear the current arriving could prepare them for eating and digesting, possibly as when we hear and smell that somebody is preparing dinner.” Essentially, if they can’t hear, they can’t eat!
